Cold Air vs. Short Ram, Advantage and Disadvantage Options

[Shigexile]

Should i go with Short Ram or CAI? I'm in the process of making a CAI but i want to know the advantage and the disavantages (Also for the Short Ram). Like for example wich will be better acceleration or which will be better during the rain, snow. Speeking of rain, i just tried out my CAI in the rain but it lagged more then my regular filter, is that because of the water going in or just that the CAI i made sucks? I need you guy's knowledge.

i just tested in again and i notice that the engine shakes a lot now. And the acceleration is horrible. Why is this?

you dont want water going into the intake because you will Hydrolock the engine, and thats a bad thing... SRI has better acceleration because the air has to travel a lesser distance than a CAI to reach the throttle body and then be combusted... CAI will yeild more power because colder air is denser (containing more oxygen molecules) which intern gives a better air/fuel mix and bigger explosion...they both have downfalls...hope this helps

I see. Thank you very much . So the top speed, CAI has an advantage and Acceleration, the Short Ram has the up[per hand huh? I see now. That's why my car lagged. I think i will go will SRI.

[Shigexile]

so the ultimate intake will be short distanced but draws in cold air?

you might feel it is slower because when you install a cold air intake.. you loose some torque at the lower rpm, in exchange for more hp in the higher rpm..

but in toyota's cold air intakes dont help much, because the stock air boxes are not as restrictive as honda.

well the best of both worlds is get a downpipe on the SRI and u get cold air still and dont have to worry about getting hyrdolock.... unless u submerge your car lol :-/

*edit* well err im meaning a metal type of pipe welded or sealed onto the end of the SFI and lead down to the lower part of the engine

I think the best setup would be a short ram with a box around it connected to a cold air extension that goes into the fender. not really worth the trouble for 1/2 a hp though

Short Ram:
- Cheaper
- Easier install
- Readily Available
- Less horsepower

CAI
- More power
- Harder to route
- Not available for a gt without modifications

a short ram is going to give you less horsepower then the stock air box would(technically the stock air intake IS A CAI). It will be drawing in warm air, as the stock air box wont. Think about it. the ventilation in the celica is very poor, and its around parts that produce hot air. It is hot as **** where that air filter is going to be on your SRI. Your going to be drawing in hot air to your engine. another words its a downgrade. so it be pointless IMO to get SRI, unless your only motive would be the sound it produces.

I didnt notice any less acceleration lag with my CAI, if anything better pickup and a tad bet more power overall. And it sounds awesome! talk to 95celgt if your intrested.

after I intalled my short ram I had better responce with acceleration. Also my mileage got better by about 1-2 mpg. See profile for pics

[flipside97LTD]

Obviously it's easier to make a SRI, so that's definetly a plus. But at the same time, it's not hard to build a CAI, and it does have greater gains in horse power. It took me about 1.5 hours.

I have a SRI on both my 97 and my 92 Celicas...I did it for sound and to see if I actually get better gas mileage...too bad I drive like a jerk so I really can't guage my gas mileage..aha

[sinner96ST]

just installed my short ram, and i can back shid's comments about it.

there is a duct coming from the wheel well right under the fusebox, that air travels through. so, it's not getting *JUST* hot air.

Besides, it's not the actual filter that gets hot, it's the PIPING that gets to obscene temps.

So, my thinking would be, either way, if you install a short ram OR cai, when the air hits that pipe near the TB, it will be almost the same temp.




i altered this pic to show you what i'm talking about. see the duct below the fusebox? that has air coming in to it from the fender area, just like the stock airbox setup.

[ghostdog]

this is kind of unrelated but I question how much cold air the stock 'cold air' extension gets. if you take it out you'll notice its closed off at the bottom, so how exactly does it work to bring cold air into the airbox?

[Blakout16]

its actually gets a good fair amount of cold air comming from it... the pipe leads straight from the lower bottom of the wheel well.... i remember seeing it down there when i did a clutch job.
